Answer:
False!
Explanation:
Regulation of the temperature in any body is mostly done by the nervous system. But if a dog wants to maintain homeostasis they will pant as a way to cool off. This physical behavior is their way for regulating their internal temperature, which keeps them from overheating
Discuss how population size and natural events could limit the resource availability in an ecosystem.
Which of the following statements about metabolism are true? 1) Catabolism is the process in which complex substances are broken down, yielding a net output of energy. 2) Metabolism is an integrated system in which many of the same reactions participate in degradative (catabolic) and biosynthetic (anabolic) pathways. 3) Anabolism involves the synthesis of polymeric biomolecules and complex lipids from monomers such as fatty acids and nucleotides. 4) All organisms require an external source of energy, such as glucose or sunlight, for metabolic energy.
Answer:
the answer is 1), 2) and 3)
Explanation:
Metabolism can be defined as all the chemical reactions inside a cell that are required to carry out cellular functions (e.g., reproduction, growth, development). The metabolic reactions can be divided into anabolic and catabolic reactions. Anabolic reactions refer to metabolic reactions that require energy in order to construct new molecules from smaller ones (i..e., biosynthesis). Anabolism comprises endergonic metabolic pathways which are fueled by the use of energy (e.g., cellular ATP). On the other hand, catabolic reactions refer to metabolic reactions where larger molecules are separated to form smaller ones. Catabolic reactions are exergonic because they do not require energy (for example, reactions involved in cellular respiration).
How can gene flow, genetic drift, and natural selection all influence macroevolution?
Answer:
Macroevolution refers to large-scale evolutionary changes that break the species barrier and can give rise to new species and even affect higher taxonomic groups.The basic evolutionary mechanisms migration, genetic drift and natural selection can produce important evolutionary changes if given enough time.Large groups and macroevolutionary trends originate in gradual, adaptive stages, as a product of natural selection acting at the level of individuals , but operating for much longer periods of time.All depends on the mutations originating new alleles or genes, which imply the existence of very different characters from the pre-existing ones, and that these different characters are selected because they imply a better adaptation to the environment.
Explanation:
Macroevolution refers to the evolutionary changes that occur on a large scale, such as the genesis of high-ranking taxonomic groups: the appearance of species within their taxonomic groups, the appearance of evolutionary trends, the acquisition of anatomical characteristics that characterize the groups.For there to be an evolutionary change, then, new properties must emerge that constitute a new species. Evolution is a process of changes at the species level, distinct from those that occur in each individual organism. Gene flow is the transfer of alleles of genes from one population to another. Contributes to variation and diversity of individuals. Evolution is then the change of allelic frequencies over time.Macroevolution takes place through the process of natural selection, that is, the differential reproduction of individuals, and adaptive improvement over a very long period of time. This type of evolution is based on interpreting the appearance of new species or large groups, as well as mass extinctions, with the subsequent proliferation of new groups. The evolutionary changes that determine the origin of body plans are based on macromutations on which natural selection acts.

Human red blood cells can live from two to four months without a nucleus, and yet they continue to synthesize hemoglobin. This Group of answer choices is a chemical process that does not require continued living pathways; the red blood cells are essentially dead after they lose their nuclei. suggests that there is a low level of RNA polymeraseto degrade the mRNA. means that the necessary ribonucleases are continually translating DNA. means that both the necessary mRNAs must persist and there must be a low level of RNA-degrading enzymes present.
Answer:
means that both the necessary mRNAs must persist and there must be a low level of RNA-degrading enzymes present
Explanation:
Mature red blood cells (also known as erythrocytes) don't contain nuclei. The red blood cells that enter the bloodstream eject their nuclei in order to have more space for transporting hemoglobin, a protein whose main function is to bind molecular oxygen. Erythrocytes have a life span period of three (3) to four (4) months. During this period, the mRNA of the hemoglobin genes must remain intact in order to synthesize hemoglobin proteins (i.e., their subunits). Moreover, in mature red blood cells, the levels of the enzymes involved in the degradation of cytoplasmic mRNA (ribonucleases) must also be low to avoid bulk mRNA degradation.

- Which occurrence is the result of the cell cycle in unicellular organisms?
A. cell repair
B. cell growth
C. cell replacement
D. cell reproduction
Answer:
D
Explanation:
Cell reproduction is the result of the cell cycle in unicellular organisms. The correct option is D.
What is cell reproduction?Cells split to produce multiple cells with similar, if not identical, contents. This process is known as cellular reproduction.
Nuclear division during mitosis produces two somatic cells that are genetically identical to the parent cell and have the same genetic complement.
Asexual reproduction in prokaryotes takes the form of cell division in unicellular organisms.
When an organism splits in half, it creates two totally distinct daughter cells, a process known as binary fission. The daughter cells are identical to the parent cells genetically.
Most of the time, Paramecium reproduces asexually via budding, however in poor circumstances, they produce sexually.
Unicellular organisms have a variety of asexual reproduction strategies, including multiple fission, fragmentation, and budding.
Thus, the correct option is D.

Explanation:
Quantity, information content, packing and replication of chromosome are the major differences that is present between the organization of DNA in viruses and bacteria as compared to eukaryotes. The quantity of DNA in bacteria and virus is less than eukaryotes. In virus and bacteria, DNA is arranged into a single circular chromosome while on the other hand, in eukaryotes, DNA is arranged into several linear chromosomes.

Isabel is 16 years old and preparing to take a final exam. Her good friend has a list of the possible essay questions that were taken from the teacher's desk and asks Isabel if she would like to look at it. Isabel chooses not to look at the essay questions. According to Kohlberg, why might Isabel have made this decision? Be sure to describe the stages of Kohlberg's theory of moral development in your response.
Answer:
According to Kohlberg, Isabel might have made this decision in order to maintain social order.
Explanation:
There are six stages in Kohlberg's theory of moral development. They include;
Stage 1 Pre-conventional (Common among children under the age of 9)
Obedience and punishment orientation Self-interest orientationStage 2 Conventional (Common among pre-teens, teens, and some adults)
Interpersonal accord and conformity Authority and social-order maintaining orientation:This is the stage Isabel is in. Isabel recognizes that the law is against cheating and she reasons on how her own personal actions would negatively affect the society. Therefore, she choses to play her own role by desisting from cheating even if her friend is doing it.

I NEED HELP PLZ ITS DUE TODAY. The sun produces a great amount of energy with sound and lights. We enjoy the sun's light and heat waves on Earth, but cannot hear any sound of the sun. Explain this phenomenon in terms of mechanical waves and electromagnetic waves. (10 Points)
Answer:
See explanation
Explanation:
First of all, we have to know the difference between a mechanical wave and an electromagnetic wave.
A mechanical wave requires a material medium for propagation. It does not travel through space. An electromagnetic wave does not require a material medium for propagation and it can travel through space.
Light and heat are electromagnetic waves. They both belong to the electromagnetic spectrum. On the other hand, sound is a mechanical wave.
While heat and light can travel through space, sound can not because it is a mechanical wave. Sound has to pass through gas molecules and there is no gas in outer space.
Hence, we enjoy the sun's light and heat waves on Earth, but cannot hear any sound of the sun.
Fruit color in a particular plant is controlled by a set of three quantitative traits that work in an equal and additive manner. Each trait has two alleles (i.e., A and a); each allele represented by a capital letter produces one dose of yellow pigment, while alleles represented with lower case letters do not produce any pigment at all. How many different shades of yellow fruit color are there
Answer:
7
Explanation:
The number of distinct shades of fruit color would be 7. It is given that the color is dominated by a group of three QTL(quantitative traits) with each trait having two alleles(A,a). Out of these two alleles, one represented by a capital letter(A) generates a single dose of yellow pigment while the latter represented by a smaller case letter(a) does not generate any pigment. Since there is no environmental effect, the number of various yellow shades would be 7 through the combinations of yellow and colorless pigments(A/a, A/a, A/a, A).
